An elderly disabled Tasmanian man who died after crashing his mobility scooter may have survived if he was wearing a helmet, a coroner has found.
Keith Thomas Stewart, 73, died in hospital on July 4 last year after suffering a serious head injury in the accident three days earlier.
Mr Stewart, who had an intellectual disability, was living in aged care at the Beaconsfield District Health Service (BDSU) in the state's north when he set off on a morning trip.
But he lost control at the bottom of the home's steep driveway and collided with a parked car.
CCTV from the area showed Mr Stewart wasn't wearing a helmet.
"It is certainly possible that had he been (wearing a helmet) he would not have suffered the injuries which caused his death," Coroner Simon Cooper wrote in findings published this week.
Mr Stewart was given the scooter in 2014 by his sister-in-law who gave a set of guidelines to BDSU outlining he wear a helmet and high-visibility vest when driving, and that he only operate it on the flattest pathway possible.
Mr Cooper was satisfied BDSU took all reasonable precautions to ensure Mr Stewart operated the scooter safely.
Mr Stewart used the scooter once or twice a week and usually drove down the driveway, Mr Cooper noted, adding staff had witnessed him using it safely.
